Generative AI: A Creative New World

What: A comprehensive overview of the generative AI landscape at the application layer. Beyond the most well known text and image generation applications, we are seeing the emergence of code, speech and 3D image generation.

Facebook Research - Introducing Make-A-Video: An AI system that generates videos from text

What: Meta AI have released a model which turns text into short form videos, building upon recent successes by many models to generate images from text prompts. Th opportunities this unlocks for content creation is astounding. Google wasted no time in responding and have released their own text to video model. Generative AI is moving at a rapid pace, will safeguarding be able to keep up?

AudioLM: a Language Modeling Approach to Audio Generation

What: Google AI have released a model that can generate realistic and consistent audio given a few seconds of either speech or piano playing. This represents a significant milestone given the complexity of generating both realistic audio alongside audio that is stylistically consistent with initial audio inputs.

The team also trained a classifier that can detect between synthetic audio vs real audio which is a great demonstration of responsible AI.

Cool companies found this week

Climate

Everest Labs - An AI-Enabled Operating System for Recycling. They have recently raised $12m to continue their journey of using AI to detect waste from recycling.

...and Finally

Despite the company claiming above that they have authorisation to create a deepfake, Bruce Willis has now claimed that this authorisation was never provided.

AI/ML must knows

Foundation Models - any model trained on broad data at scale that can be fine-tuned to a wide range of downstream tasks. Examples include BERT and GPT-3. (See also Transfer Learning)
Few shot learning - Supervised learning using only a small dataset to master the task.
Transfer Learning - Reusing parts or all of a model designed for one task on a new task with the aim of reducing training time and improving performance.
Generative adversarial network - Generative models that create new data instances that resemble your training data. They can be used to generate fake images.
Deep Learning - Deep learning is a form of machine learning based on artificial neural networks.
